Just bc electric fence is available doesn't mean it was ever meant to be permanent fencing.
You know, stuff with animals just costs$. You wouldn't think of not worming or giving yearly boosters bc you can get away with not doing it and it's cheaper to NOT do it.
Honestly I've had bad experiences with electric fencing. You must maintain it and horses do get injured with it in a way that they don't get injured with wood or metal bar fencing. This takes away from my training/riding time.
My fencing takes minimal maintenance and that's why I bought it, but the TB broodmare farm close to me, with big $bucko mares, uses wooden fencing. Every year they have to replace planks, but they've been breeding horses for a LONG time and I respect them for their choice.
I am sorry to be honest, but keeping horses in your back yard is just expensive.
You've obviously had bad experiences with electric, and I imagine I would re-think fencing if I did, too, but I'm sure that a large number of people will agree that it is not more dangerous and often less dangerous than other types of fencing.
Electric fencing is made to be permanent fencing, most people use it that way, and is meant to keep horses away
from the fence entirely. We use one or two strands of electric polyrope around our pastures and none of our horses, including our weanling, have ever gone under, over, or through it, even when we have no power for a day or the rope is sagging to a couple feet from the ground because of the weight of sleet and they could easily just step over it. The only maintenance it requires is removing the occasional branch that falls on it.
Some folks have horses that will run through or jump anything, and for them, you do need an expensive fortress of a fence, but if you have horses that mind the fence, you're golden with a lot less and it does not mean you're being cheap, just practical.
